I suggest spending $150 to $200 for a decent camera. Cheaper cameras have cheaper, poor quality parts. Another suggestion, what ever camera you choose, purchase good quality batteries.

Bushnell offers a two year manufacture warranty. Most others only offer one year. Many dealers only offer up to 90 days.
Some good buys can be had on EBay. As a word of caution, if the EBay seller isn't an authorized dealer by the manufacture, there is no warranty. Good luck in your choice.
